What are the quality features of EN 10025-6 S690QL high strength steel

Steel pipe refers to the steel with openings at both ends and hollow section, and its length is larger than that of surrounding steel. According to the processing technology, it can be divided into seamless steel pipe and welded steel pipe, EN 10025-6 S690QL high strength steel. The production methods mainly include hot rolling, cold rolling, extrusion, cold drawing, forging, welding, etc. The size range of steel pipe is very wide, from capillary with small diameter to large diameter pipe with several meters. Steel pipe can be used for pipeline, thermal equipment, mechanical industry, petroleum geological exploration, container, chemical industry and special purpose.

The company is committed to providing customers with high-quality and low-cost EN 10025-6 S690QL high strength steel steel products as the goal, striving to create value for customers as its own responsibility. With advanced Kaiping processing equipment and strong logistics distribution system, the company can meet the needs of customers at any time. The company has the advantages of EN 10025-6 S690QL high strength steel complete specifications, low price and fast distribution, With the service concept of keeping promise and valuing quality, it has won the trust and unanimous praise of the majority of users. The scale and strength of the enterprise is in the forefront of domestic metal material business units.

Nickel element is mainly used to form and stabilize the austenite structure, so that the EN 10025-6 S690QL high strength steel steel has good mechanical properties, corrosion resistance and process performance. Molybdenum can quickly passivate stainless acid-resistant steel, and improve the corrosion resistance to solutions containing chloride ions and other non-oxidizing media. Titanium and niobium are usually used to fix the carbon in alloy steel and make it generate stable carbides to reduce the harmful effect of carbon on the corrosion resistance of alloy steel.

EN 10025-6 S690QL high strength steel, Stainless steel relies on a very thin, solid, fine and stable chromium rich oxide film (protective film) formed on its surface to prevent oxygen atoms from continuing to infiltrate and oxidize, so as to obtain the ability of corrosion resistance. Once the film is damaged for some reason, the oxygen atoms in the air or liquid will continuously penetrate or the iron atoms in the metal will continuously separate, forming loose iron oxide, and the metal surface will be continuously rusted.

To provide customers with the most satisfactory service and realize the win-win of economic and social benefits, our company promises to provide excellent EN 10025-6 S690QL high strength steel products in this bidding, and in line with the attitude of being serious and responsible to customers, before sending goods to users, the EN 10025-6 S690QL high strength steel technical personnel shall confirm that there is no fault in the equipment before sending goods to users, and then send goods and products to users, and formulate the following service terms.
